E) all

Which level of structure is held together only by H-bonds?

A) 1 °

B) 2 °

C) 3 °

D) b and c

E) all

Answer 1

Ans-

• B) 2

In the secondary structure formation of alpha helix and beta sheets take place by hydrogen bonding

• D) b and c

The non covalent bonds include vanderwaal forces, hydrogen bonding and hydrophobic interaction. In the secondary structure formation of alpha helix and beta sheets take place by hydrogen bonding. In the tertiary structure the hydrophobic interaction and van der waals forces stabilizes the structure
